Answer:
Constanza ocupará, como mínimo, para forrar la caja:
1350 cm²
para forrar la caja
Step-by-step explanation:
En un cubo cada una de las aristas que lo conforman miden lo mismo.
Un cubo tiene 6 caras.
La formula del área del área de las 6 caras del cubo es:
área total del cubo = a = 6*arista²
en este caso:
a = 6*(15cm)²
a = 6 * 225 cm²
a = 1350 cm²
<u>Answer:
</u>
Two required integers are 5 and 10.
<u>
Solution:
</u>
Given that a positive integer is twice another. The sum of the reciprocals of the positive integers is
We have to find the two integers.
Let assume that one integer = x
Since another integer is twice of first one, so second integer = 2x
Reciprocal of first integer =
Reciprocal of first integer =
Given that sum of reciprocal =
On solving above equation for x,
2x=10
x=5
First integer = x = 5
Second integer = 2x = 10
Hence two required integers are 5 and 10.
